Designer, setting null-representation=""

How can I set null-representation="" with the Designer? The default is null-representation="null". I click on ... and remove the null but it keeps coming back. Setting it to "" results in null-representation=""""

Thanks,
Roland

I think it worked in 1.0.x and stopped working at some time in 1.1.x. There is an issue reported: https://github.com/vaadin/designer-issues/issues/1206
Work around is to set it in declarative editor as tag attribute:

<vaadin-text-field null-representation=""></vaadin-text-field>
